Background: Lateral epicondylitis (LE), also known as tennis elbow, is the most common painful elbow condition. It affects approximately 1-3% of adults. There are various possible treatments described in the literature, but evidence to support a gold standard management protocol is lacking. Therefore, the objective of this study was to evaluate how Brazilian orthopaedists diagnose and treat lateral epicondylitis and compare these results with the available evidence.Methods: This is an observational, analytical, cross-sectional study. A questionnaire was prepared to obtain information from the participants with eight specific questions (2 on diagnosis and 6 on treatment). These questions were answered voluntarily by participants at 3 major congresses of orthopaedists in Brazil in 2018. The results were analysed in accordance with the overall number of responses and were evaluated among groups according to subspecialty.Results: We obtained a total of 501 questionnaires. Of these, 33 were excluded. The mean age was 38.67 years. The majority of respondents (91%) were male. We obtained 26.7% from specialists in hand surgery (Hand group), 36.5% from subspecialists in shoulder and elbow (Shoulder and Elbow group), and 36.8% from generalists in orthopaedics or from other subspecialties (General Orthopaedists group). For diagnosis, 24.4% did not initially request any imaging method. The most requested exam was ultrasonography (54.9%). The most prominent indication for initial treatment was physical therapy. For refractory cases, 78.3% of the respondents preferred doing a local infiltration. The most commonly used substance for local infiltrations was corticosteroids (89.6%). With respect to the surgical treatment option, 75.8% of those who recommend it prefer open techniques, and 24.2% prefer arthroscopic treatment. Of the total respondents, 12.8% did not recommend surgical treatment for LE.Conclusion: Among Brazilian orthopaedists, the Cozen test is most frequently chosen, and ultrasound is the most commonly used imaging tool. Nonsurgically, oral nonsteroidal anti-inflammatory drugs (NSAIDs) plus physiotherapy is the most popular initial therapy, and corticosteroids are the most popular type of infiltration agent. Most surgeons recommended surgery after 6 months of nonsurgical treatment, and 75.8% preferred the open technique. [ABSTRACT FROM AUTHOR]

Background: The incidence of olfactory disorders has increased in recent years, mainly related to COVID-19 infection. In Brazil, over 37 million cases of COVID-19 have been reported, and approximately 10 % of those cases continue to experience olfactory disorders for more than one month. Despite the significant negative impact on well-being, there is currently no validated instrument to assess how olfactory disorders impact the quality of life in Brazil., Objectives: This study aimed to validate the Questionnaire of Olfactory Disorders (QOD) for Brazilian Portuguese., Methods: The authors first performed translation, back-translation, expert review, pre-testing, psychometric evaluation and cultural adaptation of the English version of the questionnaire. To assure linguistic and conceptual equivalence of the translated questionnaire, 126 participants from two Brazilian states and varying degrees of olfactory loss answered the QOD and the World Health Organization Quality of Life bref (WHOQOL-bref) questionnaires. The University of Pennsylvania Smell Identification Test (UPSIT®) was used to quantify the olfactory loss. Furthermore, to evaluate the reliability of the Portuguese version a test-retest was performed on a subgroup of patients. The authors observed a high Cronbach's alpha (α = 0.86) for internal consistency of the quality of Life (QOD-QOL) statements., Findings: As expected, there was a negative correlation between QOD-QOL and UPSIT® (Spearman's ρ = -0.275, p = 0.002), since QOL score increases and UPSIT® score decreases with worsening of olfactory function. Correlations were moderate between QOD-QOL and WHOQOL-bref mean (Spearman's ρ = -0.374, p < 0.001) and weak to moderate between the QOD-QOL and Visual Analog Scale of the QOD regarding professional life, leisure, and private life (Spearman's ρ = -0.316, p = 0.000; Spearman's ρ = -0.293, p = 0.001; Spearman's ρ = -0.261, p = 0.004; respectively)., Conclusion: In conclusion, the authors have demonstrated a high internal consistency and validity of the Brazilian Portuguese version of the QOD for evaluating the quality of life in individuals with olfactory disorders., Competing Interests: Declaration of competing interest The authors declare no conflicts of interest.

Objective: To assess Brazilian pediatric intensivists' general knowledge of extracorporeal membrane oxygenation, including evidence for its use, the national funding model, indications, and complications., Methods: This was a multicenter cross-sectional survey including 45 Brazilian pediatric intensive care units. A convenience sample of 654 intensivists was surveyed regarding their knowledge on managing patients on extracorporeal membrane oxygenation, its indications, complications, funding, and literature evidence., Results: The survey addressed questions regarding the knowledge and experience of pediatric intensivists with extracorporeal membrane oxygenation, including two clinical cases and 6 optional questions about the management of patients on extracorporeal membrane oxygenation. Of the 45 invited centers, 42 (91%) participated in the study, and 412 of 654 (63%) pediatric intensivists responded to the survey. Most pediatric intensive care units were from the Southeast region of Brazil (59.5%), and private/for-profit hospitals represented 28.6% of the participating centers. The average age of respondents was 41.4 (standard deviation 9.1) years, and the majority (77%) were women. Only 12.4% of respondents had taken an extracorporeal membrane oxygenation course. Only 19% of surveyed hospitals have an extracorporeal membrane oxygenation program, and only 27% of intensivists reported having already managed patients on extracorporeal membrane oxygenation. Specific extracorporeal membrane oxygenation management questions were responded to by only 64 physicians (15.5%), who had a fair/good correct response rate (median 63.4%; range 32.8% to 91.9%)., Conclusion: Most Brazilian pediatric intensivists demonstrated limited knowledge regarding extracorporeal membrane oxygenation, including its indications and complications. Extracorporeal membrane oxygenation is not yet widely available in Brazil, with few intensivists prepared to manage patients on extracorporeal membrane oxygenation and even fewer intensivists recognizing when to refer patients to extracorporeal membrane oxygenation centers.

Background: Limited research has examined mobile phone-based platforms for survey recruitment, especially during the COVID-19 pandemic in Brazil. Our objective was to investigate the feasibility and representativeness of mobile phone-based advertisement during a preliminary study about COVID-19 vaccine hesitation in Brazil. Moreover, we evaluate whether the older population can be reached through mobile phone-based platforms of the survey., Methods: We conducted a study in December 2021 based on a preliminary survey about the COVID-19 vaccine hesitation in Assis, Brazil, Sao Paulo state. From a list of the adult population hesitant about the second dose of the COVID-19 vaccine, we sent a mobile phone-based advertisement inviting the participants to answer the survey for one week. The respondent's data were collected in a Google form platform. The comparison between the target population and the respondents was made using the Chi-squared test and the Welch's test, using a P-value of 0.05 as significative., Results: The response rate was 9.99% after one week. The mean age of the respondent group was 33.97 (SD 14.99) and 35.05 (SD 14.19) of the population, with a P-value of 0.192 and a Cohen's d coefficient of 0.0754, corresponding to a small effect size between groups. We demonstrate that the mobile phone-based survey is a feasible and representative strategy during the pandemics in Brazil. Moreover, the older population respondent was representative., Conclusion: We achieved a representative sample of respondents using the mobile phone-based survey in Brazil. Furthermore, it was representative of all sociodemographic and health characteristics assessed. Finally, these findings suggest that the method is a highly feasible and economical means of recruiting for survey research., (Copyright © 2022 Elsevier B.V. All rights reserved.)
